Syn.: Biatora lurida (Ach.) Stenh., Lecidea lurida Ach., Lecidea petri (Tuck.) Zahlbr., Mycobilimbia lurida (Ach.) Hafellner & Türk, Psora lurida (Ach.) DC., Psora petri (Tuck.) Fink

Lichenised.

Substrate: calciferous rocks, calciferous soil

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a calcicolous, ecologically and altitudinally wide-ranging species, whose development often starts in fissures of the rock subject to temporary water seepage after rain, with a wide altitudinal range; widespread throughout the Alps.
